Problems With update 1.6?
1.can't login to Noobstown? -> Noobstown might still be on update 1.5_01 because their plugins might have not got updated for update 1.6
2.How could i fix this if i have already updated minecraft? -> Well what you could do is either if u have it still. Copy the jar file of update 1.5_01 goto run -> &APPDATA% -> .minecraft -> bin and in there is your 1.5_01.jar file copy it and paste it somewhere other then that folder then if you want to you can update if you want to. If you want to change back to 1.5_01 just delete the 1.6.jar update and replace it with the 1.5_01.jar file. If you do not have it i will put a link onto this post in the future to get the 1.5_01.jar file.
